Su (2) × Su (2) Harmonic Superspace and (4,4) Sigma Models with Torsion

Abstract

We review a manifestly supersymmetric off-shell formulation of a wide class of torsionful (4, 4) 2D sigma models and their massive deformations in the harmonic superspace with a double set of SU(2) harmonic variables. Sigma models with both commuting and non-commuting left and right complex structures are treated.
